中文摘要:
      山坡型尾矿库由于地形以及周围环境限制,若按照传统的方法设计堆积坝,则坡度太缓,将大大减少尾矿库的有效库容。对此,以某尾矿库工程为例,尝试将岩土工程中加筋土的理念应用到尾矿库堆积坝设计中,以增大尾矿库的堆高和库容。通过GEO-studio专业软件对土工织物加筋加固尾矿库堆积坝坝坡的效果进行了模拟分析,结果表明:采用土工织物加筋后,尾矿库的堆积坡比从1︰4.5提高到1︰2.5,尾矿库的有效库容增加了38%。该研究成果可为山坡型尾矿库堆积坝设计提供借鉴和参考。
英文摘要:
      Due to the restriction of surrounding terrain and environment, the slope of tailings embankment designed by the traditional method is too slow, which greatly reduces the effective capacity of the hillside tailings pond. This paper took a tailings pond project as an example and attempted to apply the concept of reinforced soil in geotechnical engineering to the design of tailings embankment. This measure was designed in order to increase the pile height and storage capacity of tailings pond. Meanwhile, GEO-studio professional software was used to simulate and analyze the effect of geotextile reinforcement on the slope of tailings embankment. Results indicated that the slope ratio of tailings embankment after geotextile reinforced was significantly improved from 1︰4.5 to 1︰2.5. The effective storage capacity of the tailings pond increased 38%. The research results can provide reference for the design of hillside tailings embankment.
